Over 10 years, the testosterone-treated men lost 20.3 percent of their baseline weight (50.5 lb; 22.9 kg); their waist circumference dropped by 12.5 cm (4.9 in). BMI decreased by 7.3 kg/m2, and the waist-to-height ratio decreased by 0.07.
By contrast, the untreated men gained 3.9 percent of their baseline weight (3.2 kg; 7.1 lb), and their waist size increased by 4.6 cm (1.8 in). In this group, BMI increased by 0.9 kg/m2, and waist-to-height ratio increased by 0.03.
During this time, 12 (4.4 percent) men in the testosterone group died, while in the untreated control group, 57 deaths (30.2 percent), 47 myocardial infarctions (24.9 percent) and 44 strokes (23.3 percent) occurred.
